Acceleration
... Acceleration • Answer: The grape would be traveling the fastest just as it hit the water (or ground) because objects in free fall accelerate all the way down (or until they reach terminal velocity. • Terminal velocity is the point at which the force of gravity is opposed by an equal force due to air ...

... In activity 3.2 we found that the force of gravity causes the velocity of a cart to increase as it rolls down a ramp. We now calculate the rate of change in velocity (the acceleration) of the cart as it rolls down the ramp. 1) Use two blocks to support the wooden ramp. Hold the cart at rest at the t ...

... 1. In other words, if you don’t have a force, or net force is zero, you can’t have acceleration. 2. If you’re stopped, you stay stopped. If you’re moving, you stay moving at the same speed in the same direction. 3. So, if you’re going 50 mph, you keep going 50 mph unless there’s a force on you. 4. T ...
