Why can you exert greater force on the pedals of a bicycle if you pull up on the handlebars?
because the muscles in your arms pulling on the handle bars causes an equal and opposite reaction from the bars acting on your arms in a direction toward the bike. this force counteracts some of the upward force from the equal and opposite reaction from the pedals due to you pushing down with your feet. in other words, it allows you to counter some of the force by involving muscle from your arm in the force to hold you down to the bike.
You are using the muscles in your arms to pull your weight downwards on the pedals with a greater force than just using your legs alone. You are using your legs and arms in tandem to pedal.

What objects will the earth exert a greater gravitational pull than on a baseball?
A bicycle A truck . A camel
Why was the gear connected to the pedals larger than the gear connected to the wheel?
The gear connected to the pedals is larger than the gear connected to the wheel to create a gear ratio that enhances torque and efficiency. This configuration allows the rider to exert less force on the pedals while achieving greater rotational speed at the wheel, making it easier to accelerate and climb hills. Essentially, the larger gear multiplies the pedaling force, translating to more effective movement of the bicycle.
What objects will the earth exert a greater gravitational pull than on a bicycle?
The Earth will exert a greater gravitational pull on objects with greater mass, such as cars, buildings, and mountains, compared to a bicycle. This is because the force of gravity between two objects is directly proportional to the mass of the objects, so the more massive an object is, the stronger the gravitational pull it experiences.
List three forces that exert when riding a bicycle?
tension , compression and friction
If you exert 200 joules in peddling a bicycle on level ground what is the work output?
200 joules
What liquid would exert a greater buoyant force?
A liquid with higher density will exert a greater buoyant force. This is because buoyant force is proportional to the density of the liquid displaced by the object.
Why is it hard to steer a bike whilst holding the center?
If you exert a force of 100 newtons , and your hands are 10cm (0.1m) from the pivot(the center of the handlebars, the formula is force(100)xPerpendicular distance (0.1) the force would be 10 newtons , but if you increased the distance your hands are from the center (e.g. to 50cm away) the force would be 50 newtons , So, the greater the distance from the center , the greater the turning force (moment).
What objects on earth exert a greater gravational pull than your whole body?
The Earth itself exerts a greater gravitational pull on objects than an individual's body, as well as massive celestial bodies like the Sun and the Moon. Additionally, large rocks or structures with significant mass can also exert a greater gravitational pull due to their mass.
Which object does gravity exert a greater force on?
The one with the greatest mass that is closest to the surface of the Earth.
How does a bike use energy to propel forward?
A bike uses energy to propel forward by converting the energy from the rider's pedaling into kinetic energy. When the rider pedals, the chain transfers the energy to the wheels, causing them to turn and move the bike forward. This process is powered by the rider's muscles and the force they exert on the pedals.
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
As the temperature increases, the air molecules inside the bicycle tire gain more energy, leading to an increase in their speed. This increased speed causes the molecules to exert greater pressure on the walls of the tire, resulting in an increase in the tire pressure.
