How is Acceleration related to speed?
Acceleration is the rate of change of velocity (not speed). Acceleration is the rate of change of velocity over time. Velocity is defined by speed and direction. A satellite orbiting the earth at a constant speed is still accelerating because gravity is making it travel in a circle (or ellipse) and consequently its direction and therefore its velocity is constantly changing.
Can an internal force cause acceleration in a body?
Yes, an internal force can cause acceleration in a body.
What cause acceleration to decrease?
Acceleration can decrease due to friction, air resistance, or an opposing force acting in the opposite direction to the motion. An increase in mass or a decrease in the force applied can also cause acceleration to decrease.
What surfaces will a toy car travel the least distance?
A toy car will travel the least distance on surfaces with high friction, such as rough terrain, carpet, or surfaces with obstacles that cause resistance. Smooth surfaces like glass or ice may also reduce the distance traveled due to lack of traction.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Is the acceleration cause by the gravity constant?
acceleration caused by gravity is not the same because it varies from the mass and the distance betwwen the two objects
Why do you have to have negative acceleraton?
A negative acceleration, or deceleration, is the cause of unbalanced forces, where the force opposing the direction of travel is greater than the force along the direction of travel.

Can an internal force cause acceleration in a body?
Yes, an internal force can cause acceleration in a body.
Will leaving a force constant and doubling the mass of an object cause the acceleration to double?
Just the opposite. It will cause the acceleration to drop by 50%.
If a ball is thrown in space and on earth which ball will travel the greatest distance?
Naturally the ball in space will travel the longest distance as long as it does not bump into something along the way. Gravity on earth will cause the ball thrown to fall back to earth.
Unbalanced forces on an object cause what?
acceleration
Does torque cause angular acceleration?
Yes.
What cause acceleration to decrease?
Acceleration can decrease due to friction, air resistance, or an opposing force acting in the opposite direction to the motion. An increase in mass or a decrease in the force applied can also cause acceleration to decrease.

What types of forces cause acceleration?
Forces such as gravity, friction, tension, and applied forces can cause acceleration in an object. When an unbalanced force acts on an object, it can cause the object to accelerate in the direction of the force.
