Forces and Motion - Unit Review | Baamboozle - Baamboozle

TRUE or FALSE: In a collision between A and B, increasing the mass of A will always increase the acceleration of B.

FALSE: It will increase the FORCE between the two objects, but will not directly affect the acceleration. The acceleration in a collision is dependent on FORCE

Alex is pushing on a box. Why doesn't the box move even though Alex is pushing on it?

The force of friction is balancing the force of Alex's push.

TRUE or FALSE: When two objects with different masses collide, only the larger object exerts a force on the smaller one, causing it to move.

FALSE - both objects exert equal and opposite forces on each other

Check

Two unequal forces are exerted in opposite directions on an object. Will the object accelerate?

Yes - the forces are unbalanced so the object will move in the direction of the stronger force.
